The question

Find the cartesian form of the principle value of:

My attempt

//uh oh, this is on a branch cut!

How do I proceed, if the principle Log is not defined on the negative real axis?

Thank you.

Not sure there's a problem here. The only place Log isn't defined is at .

Thanks, that's the answer I eventually got. However the book answer is . I think they just added to the principle argument (not sure why).
